XXX.—Contributions to the history of cyanuric chloride and cyanuric acid

RECEX'T experiments on cyanuric acid and melamine have shown beyond much doubt that these substances are normal, and not is0 in their constitution.Nevertheless, it seemed interesting to extend the data upon which this view rests by the preparation and study of other syanuric derivatives.With this object, I have investigated the action of cyanuric chloride on the salts of various organic acids.Podium Acetate.-If this salt be heated with cyanuric chloride in a closed tube for eight hours at loo", a reaction takes place, and on opening the tube the characteristic odour of acetyl chloride is perceived.By treating the conteuts of the tube with cold ether, the
